A:Answer The AT92ECD would be a suitable replacement for the DR400E. The only difference between these is that the DR400, which was our best P-mount model at the time, used a nude mounted tip and the 92ECD uses a bonded tip. Currently, we do not make a P-mount model cartridge of this quality. If you are interested in replacing the stylus assembly only, not the entire cartridge with stylus, consider the following replacement stylus https://www.lpgear.com/product/ATN3472NE.html .
